Leaf-sheath oral hairs lacking, or ciliate. Leaf-sheath auricles erect. Ligule an eciliate membrane. Leaf-blades ascending; flat, or conduplicate, or involute; 2–6 cm long; 1–2.5 mm wide.
INFLORESCENCE Inflorescence a panicle.
Panicle contracted; linear; 2–7 cm long. Primary panicle branches bearing spikelets almost to the base.
Spikelets solitary. Fertile spikelets pedicelled.
FERTILE SPIKELETS Spikelets comprising 1 fertile florets; without rhachilla extension. Spikelets lanceolate; laterally compressed; 3–4 mm long; falling entire. Spikelet callus pubescent; base obtuse.
GLUMES Glumes similar; reaching apex of florets; thinner than fertile lemma. Lower glume lanceolate; 3–4 mm long; 1 length of upper glume; membranous; 1-keeled; 3 -veined. Lower glume apex acute, or acuminate; muticous, or awned; 1 -awned. Lower glume awn 0–3 mm long. Upper glume lanceolate; 3–4 mm long; 1 length of adjacent fertile lemma; membranous; 1-keeled; 3 -veined. Upper glume apex acute, or acuminate.
FLORETS Fertile lemma oblong; 3–4 mm long; cartilaginous; without keel; 3 -veined. Lemma margins involute; interlocking with palea keels. Lemma apex acuminate; muticous, or awned; 1 -awned. Principal lemma awn straight; 0–5 mm long overall. Palea with auriculate flaps; 1 length of lemma; cartilaginous; 2 -veined. Palea keels winged (below); narrowly winged.
